Develop Base Layer Bottoms with ZESTLET

ZESTLET develops thermal base layer bottoms in Sialkot for uniform suppliers, outdoor brands and private-label buyers. Specify the intended use, waistband, rise, inseam, ankle cuffs and knit fabric. Review the actual material and fit beneath the intended outer trousers before approving production.

Fit beneath the intended trousers

Specify waist, hip, front and back rise, thigh, inseam and ankle opening. Review sitting, bending and knee movement under the intended outer trousers so the base layer does not bunch or restrict the wearer.

Review waistband and seam comfort

Agree elastic width and tension, waistband construction, seam placement and label treatment on the sample. Check that the chosen finish and fit work together rather than approving the elastic separately from the garment.

Keep the set consistent

Use the same approved knit and shade reference where tops and bottoms form one range. Review wash behavior, size grading and pack combinations separately for each piece, with clear labels for mixed sizes if requested.

Thermal Bottom Customization

  • Waistband width and elastic
  • Rise, inseam and leg fit
